I have just replaced the headgasket on my 88 GA15E Pulsar and found the front main bearing is leaking like a mo fo. As in drip drip drip all gone in 30 minutes of driving.

Can anyone advise me on what is required to replace the main bearing/seal? Is there an external seal at all or is it just a bearing?
Do I need to completely dismantle the engine down to the block, or can it be done with a simple replacement of a seal from outside of the engine?

Thanks for any advice,

I'm not sure on the GA15E, but on the GA16 it has a seal that can be accessed quite easily. Do you know if you have a timing chain or a belt? If it is a chain, your seal will be on the outside and accessable by pulling the lower main crank pulley. If it has a belt you will most likely have to pull the timing cover, and the lower timing sprag to get to the seal.

thanks for the info. the crankshaft bolt was an absolute bastard to remove, but once that and the pulley was pulled it was a piece of piss to change the $8 seal. cheers!
